multi-hop ssh port forwards?

[Bill McGonigle]

Has anybody figured out how to do ssh tcp port forwards across multiple 
hops?

I'd like to ssh -L from any client, to a known server, then a bastion 
host, and do port forwards from my client machine to the bastion host 
to access a port on a machine behind the bastion host.

e.g.:

Client                                 Bastion      Inside
listen <---> My Server <-|firewall|-->  Host  <---> Service
-L:8000                                             Port 80

It's trickier than I expected and haven't found much on Google.  I'm 
trying to avoid using ppp over ssh or a VPN if I can.
